There are the associative arrays and integer-indexed arrays. echo "${array[@]}" Print all elements as a single quoted string If you are using the bash shell, here is the syntax of array initialization − array_name=(value1 ... valuen) Accessing Array Values. You have two ways to create a new array in bash script. After you have set any array variable, you access it as follows − ${array_name[index]} Here array_name is the name of the array, and index is the index of the value to be accessed. Writing about Bash is challenging because it's remarkably easy for an article to devolve into a manual that focuses on syntax oddities There are two types of arrays in Bash: indexed arrays – where the values are accessible through an integer index; associative arrays – where the values are accessible through a key (this is also known as a map) In our examples, we’ll mostly be using the first type, but occasionally, we’ll talk about maps as well. But what if you need more than few variables in your bash scripts; let’s say you want to create a bash script that reads a hundred different input from a user, are you going to create 100 variables?
